NEGRONI
Design data models that power databases, APIs, and integrations.
Negroni helps professional developers standardize enterprise data models from a single source of truth, then use them to generate the schemas, APIs, and integration assets backend systems depend on.

Why enterprise developers choose Negroni
Design visually, not in JSON
Stop wrestling with complex configuration files. Negroni’s intuitive visual interface lets you design and manage even the most complex data architectures by dragging, dropping, and connecting entities. It's the fastest way to turn a whiteboard concept into a formal, collaborative blueprint.
Eliminate boilerplate with code generation
A model is only useful if it produces code. Negroni automatically generates the assets you need from your visual designs, including database schemas for any major SQL database and complete REST APIs via the Negroni Blueprint for Martini. This saves you weeks of tedious, error-prone boilerplate coding.
Built on open standards
Avoid vendor lock-in and proprietary data formats. Negroni is built on the open-source Common Data Model (CDM), ensuring your data architecture is portable, interoperable, and ready to connect with a wider ecosystem of tools and services.
What you will build
From harmonizing your enterprise data to automating API generation, Negroni gives you a single, canonical source of truth to tackle your most common and complex architectural challenges.
The Lonti ecosystem:
design, integrate, and build
Negroni, Martini, and Bellini work together to give you a complete, low-code platform for building enterprise applications without limits.
- Design with Negroni: Create the canonical data models that serve as the single source of truth for your entire application stack.
- Integrate with Martini: Use your Negroni models as the foundation for powerful backend services, integrations, and automated workflows.
- Build with Bellini: Connect your frontend UI components directly to the standardized APIs generated from your Negroni models.
It's a seamless path from architecture to execution. Design Once, Use Everywhere.
